Service HotlineGenerally, the T-bolt structure is common, and its blank shape can be completed at one time on a multi-station cold heading machine. But for T-bolts with relatively rare structures, (for example: the intersection of ¢14x42 cylinder (head) + ¢12 cylinder, the two cylinders form a 90° intersection) due to the special structure, the head Cold forming is difficult, and the traditional processing route is: die casting blank → deburring → turning processing → grinding blank diameter → wire rolling → heat treatment → surface treatment → finished product packaging.
The circlip is a common limiting element in the mechanical field, which is mainly used to limit the axial limit of mechanical parts. At present, the common circlips on the market are all circular rings with an opening. The circular ring has a certain elastic deformation capacity. When in use, the circlip can be detachably assembled to the mechanical on the part. However, the defect of the circlip adopting the one-piece ring is that the circlip is easily broken when frequently disassembled and used, and the service life is short.
The contact surface between the existing chassis and the main board is generally not a horizontal plane due to processing reasons, especially the main board is prone to warping deformation. It will increase, resulting in deformation of the motherboard and poor memory contact, affecting normal use.
At present, the nut is used as the main body through the riveting connection with the gasket, which is more and more widely used in the industrial field, especially the automobile industry. The gasket connected with the nut has two types: spring gasket and flat gasket. After the nut is tightened, the washer gives the nut an elastic force, which is pressed against the nut to make it not easy to fall off; and the function of the flat washer is to increase the contact area between the nut and the coupling, increase the friction force, reduce the pressure per unit area and protect the surface of the connected parts. Not damaged, stop the nut from loosening. Therefore, gaskets have a wide range of applications in the field of fastening connections, and it is more and more important to improve production efficiency, reduce production costs, and meet growing demands.
The flat key is a key that relies on the two sides as the working surface and transmits the torque by the extrusion of the key and the side of the keyway, and is mostly installed on the shaft. If the flat key is used for a long time or is in a bad working environment for a long time, dust, oil, etc. will inevitably be stuck between the flat key and the keyway. Since the flat key has no ejector threaded hole for disassembly, it is difficult to dismantle, and during the disassembly process A little carelessness will cause damage to the flat key.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: butterfly butterfly bolts, U-shaped clip U-shaped bolts, black long nuts, splint chamfered nuts and other products, we can provide you with products suitable for you fastener solutions.
